Insights

High rates of pretreatment and acquired drug resistance in children with HIV (CWHIV) necessitate phasing out NNRTIs. Emerging INSTI resistance underscores the need for robust drug resistance surveillance in CWHIV.

Area of Science:

  • Virology
  • Infectious Diseases
  • Public Health

Background:

  • Prevention of mother-to-child HIV transmission (PMTCT) failures and treatment challenges contribute to drug resistance in children with HIV (CWHIV).
  • Pretreatment drug resistance (PDR) and acquired drug resistance (ADR) pose significant threats to effective HIV management in pediatric populations.
  • Understanding the landscape of drug resistance is crucial for optimizing treatment strategies and improving outcomes for CWHIV.

Purpose of the Study:

  • To determine the prevalence of PDR and ADR in children with HIV (CWHIV).
  • To identify key drug resistance mutations driving PDR and ADR in CWHIV.
  • To inform strategies for managing HIV drug resistance in pediatric populations.

Main Methods:

  • A systematic review and meta-analysis of interventional and observational studies published between 2010 and 2024.
  • Inclusion of data on PDR and ADR in CWHIV, analyzed using random effects models.
  • Synthesis of findings from 72 studies encompassing 9973 children.

Main Results:

  • The overall prevalence of PDR was 32.48% and ADR was 61.43% in CWHIV.
  • PDR was significantly higher in children who failed PMTCT prophylaxis (43.23%).
  • Nonnucleoside reverse transcriptase inhibitor (NNRTI) mutations were the primary drivers of both PDR (28.38%) and ADR (65.17%); emerging integrase strand transfer inhibitor (INSTI) resistance was observed (5.53%).

Conclusions:

  • High burdens of PDR and ADR exist among CWHIV, indicating a need to phase out pediatric NNRTIs for PMTCT and treatment.
  • Emerging INSTI resistance in CWHIV highlights the critical importance of ongoing drug resistance surveillance.
  • Optimized treatment guidelines and resistance monitoring are essential for improving long-term outcomes in children living with HIV.

Retrovirus Life Cycles01:10

Retrovirus Life Cycles

Retroviruses have a single-stranded RNA genome that undergoes a special form of replication. Once the retrovirus has entered the host cell, an enzyme called reverse transcriptase synthesizes double-stranded DNA from the retroviral RNA genome. This DNA copy of the genome is then integrated into the host’s genome inside the nucleus via an enzyme called integrase. Consequently, the retroviral genome is transcribed into RNA whenever the host’s genome is transcribed, allowing the...

Factors Affecting Drug Response: Overview01:21

Factors Affecting Drug Response: Overview

When it comes to infants and young children, they are typically administered smaller doses of medication in comparison to adults. This is primarily because their organ functions still need to fully develop, meaning their bodies are not as efficient at metabolizing or eliminating drugs. Additionally, their blood-brain barrier is more permeable than in adults. As a result, high concentrations of drugs can easily penetrate the central nervous system (CNS), potentially leading to neurological...

Immunodeficiency Diseases01:25

Immunodeficiency Diseases

Immunodeficiency disorders are conditions in which the immune system's ability to fight infectious disease and cancer is compromised or entirely absent. The immune system comprises a complex network of cells, tissues, and organs that work together to protect the body from potentially harmful invaders. When this system is deficient or not functioning properly, it leaves the body susceptible to infections, diseases, or other complications.
There are three main causes of immunodeficiency...

Treatment Resistant Cancers02:56

Treatment Resistant Cancers

Cancer is the second leading cause of death in the United States. A cancer cell is genetically unstable and hence can mutate faster. They can also modify their microenvironment and escape immune surveillance. The difficulties in treating cancer are further compounded by the emergence of rapid resistance to anticancer drugs. The most common ways to attain resistance in cancer cells include alteration in drug transport and metabolism, modification of drug target, elevated DNA damage response, or...

Pulmonary Tuberculosis I01:29

Pulmonary Tuberculosis I

Tuberculosis, often called TB, is a contagious illness primarily caused by Mycobacterium tuberculosis. It mainly affects the lung parenchyma but can also impact other body parts.
Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.

Combination Therapies and Personalized Medicine02:50

Combination Therapies and Personalized Medicine

Combining two or more treatment methods increases the life span of cancer patients while reducing damage to vital organs or tissue from the overuse of a single treatment. Combination therapy also targets different cancer-inducing pathways, thus reducing the chances of developing resistance to treatment.
The combination of the drug acetazolamide and sulforaphane is a good example of combination therapy to treat cancer. The cells in the interior of a large tumor often die due to the hypoxic and...
